By 2050, there will be more than 9 billion people on earth, and they all need to eat. In this video montage, Ken Cassman, Ph.D., University of Nebraska-Lincoln professor of agronomy, talks about the challenge of doubling the food supply in 40 years, with existing land and water. Research and technology at UNL are at the forefront of this global challenge.Strategic Discussions for Nebraska provides an opportunity for the University of Nebraska-Lincoln College of Journalism and Mass Communications to interact with our fellow Nebraskans about topics vital to the state's growth and quality of life. We also teach students research and reporting skills and conduct research projects in Nebraska communities to promote more effective communication.
